My invention aims to provide improve ments in separable iasienors oi the turn but ton type.

is a seition on the line 3-3 of Referring to. the embodiment olf my in-i vention illustrated by the drawings, l have shown a turn button fastener particularly, though not exclusively, adapted for use as a Closure fastener ior cardboard boxes and the like.

The socket is formed troni a single piece oiE metal and comprises a plate l having an elongated aperture 2 formed tlierein. The plate l is secured to the body portion ot the box l) by means o'l attaching;` prongs l; located at the periphery ot the plate l, as shown by 3 and 4i.

Ill'he stud member comprises a. relatively thin flat plate portion 5 secured to the flap 3 oit the box by attaching' prongxjs G in the saine manner as the soelret plate l. A rcsilient button or head l is secured to the plate 5 by .means ot a pair ot fingers tim-tl which are formed integral with the button or head and pass through an aperture 9 in the plate where they engage the straight eideslot a. rectangular wall 10 Surrounding; the aperture 9, ae shown by Fig. ti. The tree ends' ll oit the iingers ti-S are bent outwardly and downwardly against the plate portion The Width ot the end portions` of the lingers, which pales through the plate 5, are somewhat reduced to provide shoulders l2 at thev ed;D e ot each `linger tor engagement with that face et the plate 5 opposite that taee against which the 'free ends ll are bent, as shour'i by Fi el; l 5. llhesfehotlldefe 1.2 :nid heid button or head 7 and plate 5 in assembly, and also lnevent a1 l movement oi.: the button or head 'i' relative to the plate 5.

The lingers SMS are iree to yield with the button or head 7 so that, as; the button or head .is turned, 'the linger portions, which engiguie the wall l0, `will contract and permit-'the head to be turned from looking' to 'unlocking position, or viee-versa. lWhen the button or head 7 is in locked or unlocked poeiton, the flat sides ot the lingers engage 'the straight sides of the Wall l0, and thereby cooperate to ei'l'feetively hold the but-ton or head inA a yundetermined position so that it cannot be turned accidentally. Furthermore, the resiliency oil' the lingers 8-8 prevents rattle of the head when the 'fastener is subjected to vibration..

lllhen the stud member is seeiued to the tlap 3*, th e plate 5 is located at the .inner :tace there-ot and secured in position by the prongs (l, as shown in Figs. 3 and 4;. The button or head 7 extends :troni the plate 5 through an opening' in the :tlep 3 and extends beyond the outer face ot the .tlap so that it may engage the soelet in themanner herein after described.

The button or head 7 is preferably rectangular in outline and is adapted to pass through an aperture 13 in the body of the boliY and through the aperture 2 in the plate l. These aperturea are in alignment and both are rectangular in outline so that the head i may pass therethrough (Figs. 2 and S) and then be turned so that the longl dia1n- V,ter ot the button or head lies across the short diameter oit the aperture 2 in the plate 1, as shown in Fig. il. A- piece ot relatively .large `giungo Wire lll; may then be passed through the opening 15 in the button or head, and the ends brought together and sealed by a` sealing?,v part 16, as .illustratoi'l in Figs. l and il.

Vlhile the button or head 7 may be turned when. the sealed Wire is in place, the coin# bined dimensions of the wire and head 7 are more than the longr diameter ot the aperture l?) and therefore the fastei'ler cannot be separated Without breaking' the Seal 16.

l do not `wish to be limited to the partienlar embodiment of my invention, as illus* trated and described.

Claims:

cured to a carrying medium and a socket also secured to a carrying medium, said stud member comprising a flat plate secured 1 against one side of t-he stud-carrying mediumv and a button or head carried by said plate, said button or head passing through and being located at the opposite side of the Astud-carrying medium and having integral yieldable means secured directly to the plate for turning movementrelative thereto, said socket comprising a plate secured to the socket-carrying medium and an aperture through the plate and l carrying medium through which said button or head may pass to engage the socket and secure the two carrying mediums together and means cooper y ating between the plate of the stud member p tangular aperture therethrough, a but-ton or head partcomprising the other piece of the fastener stud unit, contractible and expansible fingers formed integral with and eX- tending from saidbutton or head part through said rectangular aperture in said plate part and engaged'with said plate part to secure said parts together while permitl. ting turning of one part relative to the other and said contractible and expansible lingers being provided with shoulders engaging one face of said plate to space said head part a substantial distance from said plate part and having their free ends bent against the other face of said plate to cooperate with said shoulders and prevent relative axial movement between said parts.

3. A turn button installation for cartons and the like comprising` a lsocket member secured to one portion of the carton and prei senting an oblong aperture therethrmigli. a stud member secured to another portion of the carton, an oblong button or head portion presented by said stud member, said button or head passing through both portions of said carton and through the a perture in said socket and adapted to be turned to secure said portions of the carton 1ogether and means for securing said fastener against separation even though said button or head be turned to fastener separating position.

4. A. turn button stud unit composed of two pieces only, one piece being in the form of a plate 5 having a rectangular aperture 9 and the other piece being in the form ot a button or head part 7 having integral spacing fingers 8 provided with means 11. and l2 at one end which engage opposite faces of the plate 5 and secure the plate 5 and button or head part 7 together and said head part 7 being located at the other end of the fingers thereby being spaced a substantial distance from said plate 5.

In testimony whereof, I have signed my name to this specification.
